Norovirus Leafy Greens Recall Tracker

How Often Do Norovirus Leafy Green Recalls Happen?

Norovirus contamination in leafy greens occurs sporadically throughout the year, with clusters emerging during fall and winter months when norovirus transmission peaks in food handling environments. The FDA has documented multiple multi-state outbreaks linked to spinach and mixed salad greens over the past decade, often traced to contaminated irrigation water or infected workers. While individual recall incidents vary in frequency, the pattern shows that leafy greens remain a high-risk category for norovirus, making real-time monitoring essential for retailers and consumers.

Which Leafy Greens Products Are Most Vulnerable?

Pre-packaged spinach, bagged salad mixes, and fresh lettuce—particularly from specific growing regions—represent the highest-risk categories for norovirus contamination. These products are vulnerable because they receive minimal or no cooking, meaning the virus survives to the consumer. Contamination typically occurs during harvesting, washing, or packaging when infected workers introduce the pathogen or when irrigation water is compromised. Raw leafy greens exported from regions with weaker food safety controls or during high-transmission norovirus seasons face elevated risk.
